Early Origins of the Trewinnard family

The surname Trewinnard was first found in Cornwall where they held a family seat as Lords of the Manor of Trewinnard in the parish of St Erth.

"The barton of Trewinnard, under which appellation this parish was taxed in Doomsday Survey, belonged to a family of this name for many generations. Two gentlemen of this family were members for the county in the reign of Edward III. ; and another, who held this property so late as the days of Henry VIII. was member for the borough of St. Ives. The last of this family who held this barton, was William Trewinnard, who was member of parliament for Helston, in the same reign. In the days of Hals, the arms of this family were extant in the glass windows of the house. From the Trewinnards this barton passed to the Mohuns." 1
